On my my Canon 7d mark II, I've started having problems where it doesn't want to pop up when I want to release it. I push in and it doesn't move until I try a couple of times. Similar when I put it back in. Sometimes it clicks and holds just like normal, but other times it won't. I don't force it in and it does it with different cards so it isn't a card specific problem.
Anyone else have the same problem? And suggestions on a potential fix I could do? Like cleaning. Otherwise, I think it means it has to go off to Canon for repairs.
